Developing a Biological Approach for Chitin Extraction from Homarus americanus Shell Waste
(2021-04-30)Lobster processing generates ~0.3M tons of shell wastes each year in Canada, which are rich in chitin, proteins, and minerals, making them valuable substrate. Among them, chitin, a natural biopolymer, has various applications ... -
Diamond resorption morphology as a fluid proxy in diamond-bearing environments: Constraints from empirical and experimental studies
(2016-07-05)Despite of numerous studies the compositions of C-O-H fluids in the mantle and kimberlites remain uncertain due to limitations of conventional methods. My study shows no correlation between internal properties in diamond ... -
Infrared water vapor continuum absorption at atmospheric temperatures
(American Institute of Physics Inc, 2005)We have used a continuous-wave carbon dioxide laser in a single-mode realization of cavity ring-down spectroscopy to measure absorption coefficients of water vapor at 944 cm-1 for several temperatures in the range 270-315 ... -
MACROMOLECULAR AND MOLECULAR CHEMISTRY OF PHOSPHORUS-NITROGEN CAGES AND RINGS
(2023-12-14)A new class of main group polymers containing three-dimensional phosphorus-nitrogen (PN) cage motifs in the backbone are described in this work. The PN cages prepared are rigid, robust but amenable to metathesis chemistry ... -
Quantifying and modelling nitrate leaching from a lettuce field in Annapolis valley Nova Scotia
(2015-04-02)Nitrate leaching (NO3-) from vegetable fields has become significant environmental issue in North America. The objective of this study was to evaluate the effect of timing and rate of nitrogen (N) fertilizer on lettuce ...
